Regimental Soldier
Apparently, if your balls hung low (and wobbled to and fro) you could swing them over your shoulder like one of these. I can't recall ever seeing any kind of soldier doing this - though I assume carelessly standing on a landmine could result in a similar effect.

It was always suggested that you could 'tie them in a knot' (presumably for 'day'wear) and 'tie them in a bow' (for more formal occasions).
